show l2vpn

show [ {l2vpn} vpls {vpls_name} | l2vpn vpws {vpws_name} | l2vpn ] {peer ipaddress} {detail} | summary }

Description

Displays Layer 2 VPN configuration and status information.

Syntax Description


l2vpn	Displays specified Layer 2 VPN information.
`vpls_name`	Displays information for the specified VPLS.
`vpws_name`	Displays information for the specified VPWS.
`ipaddress`	Specifies a Layer 2 VPN peer for which to display information.
detail	Displays additional information in comprehensive detail format.
summary	Displays summary information about all VPLS or VPWS instances.

Default

N/A.

Usage Guidelines

The show l2vpn command (without any optional parameters) displays all currently configured Layer 2 VPN instances for the switch. The summarized list of Layer 2 VPN instances is displayed in alphabetical order based on the Layer 2 VPN name. Peers are displayed in the reverse of the order they were added.

When you specify a Layer 2 VPN peer, the display includes a list of all PWs established to the peer, the PW status and PW ID, and information about each Layer 2 VPN to which this peer belongs.

The following table describes the display fields that appear when this command is entered with the detail option.

Table 1. Selected show l2vpn Field Definitions
Field	Definition
VPLS Name	VPLS instance or domain name.
VPN ID	Virtual Private Network identifier.
Source Address	Source IP address.
VCCV Status	Virtual Circuit Connectivity Verification (VCCV) feature status, which is either Enabled or Disabled.
VCCV Interval Time	Displays the configured VCCV interval time.
VCCV Fault Mulitplier	Displays the configured VCCV fault multiplier.
Redundancy Type	Displays the configured VPLS redundancy type, which is EAPS, ESRP, STP, or None.
Service Interface	Displays a VLAN or VMAN interface name.
Admin State	Displays the administrative state of the VPLS, which is either Enabled or Disabled.
Oper State	Displays the operational state of the VPLS, which is either Enabled or Disabled.
MTU	Displays the maximum transmission unit (MTU) size for the VPLS.
Ethertype	Displays the ethertype for the service interface.
.1q tag	Displays the 802.1q priority tag for the VPLS.
Peer IP	Displays the IP address for the VPLS peer.
PW State	PW State represents the state, or status, of a PW. The possible PW state values are: UP—The PW is fully operational and installed in hardware. Traffic is forwarded over PW and VPLS service VLAN/VMAN. Down—The PW is not operational and is not installed in hardware. This only happens when the VPLS instance is disabled, VPLS service is disabled, or there is no service VLAN assigned to the VPLS. No traffic is forwarded. Sgnl—The PW is in a signalling state. The PW is not operational, and no traffic is forwarded. This can occur for a number of reasons, including: No LDP adjacency to peer, No transport LSP to peer, No VC LSP to peer. Remote peer not configuredReady—The PW has been signalled, but it has not been installed in hardware. Traffic is not forwarded. The PW can be in a Ready state for a number of reasons, including: The VPLS instance is configured for EAPS redundancy, and the EAPS shared port associated with this VPLS instance is Connected. The VPLS instance is configured for ESRP redundancy, and the ESRP domain associated with this VPLS instance is Slave. The service VLAN associated with this VPLS instance is down. The remote peer has signalled that it has a fault (remote PW status). The remote peer may have a fault due to it's service VLAN being down.
PW Uptime	PW Uptime is the elapsed time that the PW has been in the UP state.
PW Installed	PW Installed is a flag to indicate whether the PW is installed in hardware or not. If the PW is in the UP state, this field is True, otherwise, this field is False.
Local PW Status	Local PW Status displays the VC status of the local PW. The values are: No Faults—No faults detected. PW-Tx—Local PSN-facing PW transmit fault. This is set if there is a problem with the VPLS transport LSP. PW-Rx—Local PSN-facing PW receive fault. This is set if there is a problem with the VPLS transport LSP. Att-Tx—Local attachment circuit transmit fault. This is set if there is a problem with the VPLS service VLAN. Att-Rx—Local attachment circuit receive fault. This is set if there is a problem with the VPLS service VLAN. Not Forwarding—The local PW is not forwarding. Look for more information in the PW State field. For example, if VPLS is configured for EAPS redundancy, the Local PW Status is Not Forwarding and the PW State is Ready whenever the EAPS Shared Port state is Connected.
Remote PW Status	Remote PW Status is the VC status of the remote PW. The values for this field are the same values as for Local PW Status.
PW Mode	PW Mode describes how the PW was configured. The values are: Core-to-Core—This VPLS instance is a core node, and the other end of the PW connects to a core node. Core-to-Spoke—This VPLS instance is a core node, and the other end of the PW connects to a spoke node. This is for HVPLS. Spoke-to-Core—This VPLS instance is a spoke node, and the other end of the PW connects to a core node. This is for HVPLS.
Transport LSP	Transport LSP is the LSP that is used to forward frames over the PW. When an LDP LSP is used as a transport, the display shows LDP LSP (Not configured). If an RSVP LSP is used, the name of the RSVP LSP being used as a transport LSP is displayed. An RSVP LSP can be specified as the LSP to use during VPLS configuration.
Next Hop I/F	Displays the interface name for the next hop router.
Next Hop Addr	Displays the interface IP address for the next hop router.
PW Rx Label	Receive label for the VPLS PW.
PW Rx Pkts	Total packets received on the VPLS PW.
PW Rx Bytes	Total bytes received on the VPLS PW.
Tx Label	Transmit label for the LSP.
PW Tx Label	Transmit label for the VPLS PW.
PW Tx Pkts	Total packets transmitted on the VPLS PW.
PW Tx Bytes	Total bytes transmitted on the VPLS PW.

The l2vpn keyword is introduced in ExtremeXOS Release 12.4 and is required when displaying VPWS information. For backward compatibility, the l2vpn keyword is optional when displaying VPLS information. However, this keyword will be required in a future release, so Extreme Networks recommends that you use this keyword for new configurations and scripts.

The following example shows the display that appears when you enter the show l2vpn command without any options:

Example

The detail version of this command now displays a “PW Signaling” line that will display “LDP” or “None (Static)”, depending on the PW configuration. The “Local PW Status” will show “--” instead of “Not Signaled”, since the PW status is not currently signaled; however, for informational purposes, any local faults are still shown. The “Remote PW Status” and “Remote I/F MTU” will always show “--”.

Since the configured labels can be changed while the current labels are in-use, there is a small window where the configured labels and in-use labels are different. If you issue the show l2vpn detail command during this window, an extra line will be output to indicate this extra information. The configured labels are noted as “pending” in this case.
